Description

If a JavaScript array is added to a View as a property of that view, and the push method is called on that array, the push operation will fail to append an element to the array. This is not a regression. This is a parity issue. This does not occur on Android or MobileWeb. Steps to Reproduce: 1. Run code:

var view = Ti.UI.createView();

var standard_array = ['Element 0'];
standard_array.push('Element 1'); // works
Ti.API.info('standard_array == ' + standard_array);

view.array_property = ['Element 0'];
view.array_property.push('Element 1'); // doesn't work
Ti.API.info('view.array_property == ' + view.array_property);

alert(standard_array + ' == ' + view.array_property);

Actual Result: Element 1 is not pushed to the array attached to the View.
